• Truck: Maximum Volume and Maximum Weigh.

• Bus : Maximum number of standing Passengers.

• Sedan : Trunk Volume.

There are employees in this agency, each employee has (Name, ID, Hire Date, Birth Date) and how many cars has he sold till now.

This agency records data about customers (Name, Id, Birth Date).

The customer can make orders the order must contain (ID, Customer, Ear, Employee).

The agency must be able to display, add, delete and modify all these data.

U must build a Capacity function for all the cars kinds, this function return a string expressing the capacity depending on the car kind.

Note:

• You must use all PR2 techniques such as (inheritance, abstract, classes, ArrayList, … )

• This must be a Form Application in C#.
